Specification of Letters Patent.

Application filed November 2, 1918. Serial No. 260,819.

To all whom it may concern:

Be it known that 1, ANDREW J. MCCOR- MACK, ing at Rochester, in the county of Monroe and Stateof New York, have invented certain Improvements in Sole-Edge-Treating Machines, of which the following descripor surfaces of a welt, a slip sole or the like superposed upon the sole proper, as is characteristic of various types of shoes. r V

The illustrated machineis especially designed to indent the upper marginal surface ofashoe sole or the stock, such asa welt or mock welt, superposed upon the shoe sole to form what are knownas impression or imitation stitches and to burnish the indentations so formed, and also to burnish the vertical edge of the sole, this operation being performed after the solehas been trimmed to final shape and being termed in the trade edge setting. It is to be understood, however, that the invention 1 in various of its aspects isnot're-" stricted to embodiment in machines of the particular'type shown.

' In the use ofa machine for indenting,

sometimes also called wheeling,-the' said upper marginal surface it is frequently necessary to change the wheels, as shoes of different styles come to the machine, the

wheels bein manufactured in many styles of depth and spacing of teeth. It is, the 019- j ect of my inventlon toprovide 'a mounting for anindentmg tool which shall permit instant removal, interchange and replacement without loss of adjustment relatively to other parts of the machine. 1

The several features of the invention, in-

cluding certain novel. arrangements and combinations of parts, 'will be described in a citizen of the United States, residthe following specification and pointed out in the claims.

Fig. 6 is a section on'the line 6-6 showing the iron adjustment; l

detail view of the blank edge Fig. 7'is a perspective of the head of the machine.

The machine has operating heads'of two types, and is a twin machine having four head's, altogether. The head 1 is mounted on the arm 2 which is caused to oscillate by any suitable mechanism not shown, driven by the pulley 6. This head carries two edge setting tools 3-, 4; for forepart and shank, respectively, and these tools are inter-'- changeable by means of the handle 5, in

well-knownmanner. The head 10 is mounted on the arm 12, which is likewise caused to oscillate-bythe mechanism of the machine.

The'arm' 12 has an arcuate slot 13 formed in one side in which slides a corresponding ar'cuate boss '14; formed'on the inner surfaceof one of two spaced plates 15. The plates 15 have rack teeth 16 at theirrear endsarranged on an arc of v a circle concentric with the arcuate boss 14. .Side plates 17 are bolted to the head 12 Outside theplates 15 bytransverse bolts 18 extending through them and the head I12.- A pinion 19 mounted in the plates 17, meshes'with the rack teeth '16 and is operated by theknurled head 20. The

bolt 18 passes throughtheplates 17 and. an

arcuate slot 21 in the plates 15 which are rigidly connectedtogether' in any suitable manner as'by'alrib 15, and maybe rotated I about the center of curvature of the rack 16: v

byturning the'knurled head 20. As will be shown later, this center issubstantiallyin the intersection of the working faces of theindenting wheel and the burnishing iron.-

In the spaces betweenthe edges ?of the plates 15 which project beyond the edges of the carrier, as the adjusting parts, such as the the head 12 are mounted the stitch indenting wheel carrier 22 and the iron 23. The carrier 22- is slidably mounted against the rib 15 between the plates 15 and has mounted upon it a spindle 24 which extends through the hole in an adjustable nipple 25 mounted upon the top edges of the structure 15-15. The nipple is exteriorly threaded for adjustment in said structure and has a smooth passage for the spindle 24. The lock nut 26 holds the nipple in adjusted position. The carrier 22 is urged downward longitudinally between the plates 15 by a spring 27 one end of which rests against the carrier and the other against the nipple 25. The carrier has a notch 28 in which a tooth 29 on a spring 30 is adapted to engage when the spindle 24 is drawn up to its utmost extent, thus holding the carrier 22 and the switch indenting wheel 31 retracted out of operative position when it is desired to dispense with it or to remove the iron 23 as will be described.

In accordance with the illustrated embodiment of the present invention, the stitch-indenting wheel 31 is held in the machine for ready removal and replacement by a toggle lever 27 at the upper end of the spindle 24:, which turns down and is pulled against the nipple 25 by the spring 27 The whole carrier 22 may be removed by straightening the lever 27 as shown in dotted lines in Flg. 1,

when the lever will slip through the nipple and the wheel carrier-22 canbe removed.

It is obvious that no loss of adjustment is involved in the removal and replacement of nipple and its lock nut, are all mounted on the head 12 and are not moved in the re moval of the carrier.

1 The iron 23 is rectangular in cross section and fits closely into the rectangular space between the square lower edge of the head 12 and the lower projecting edges of the plates 15. It is thus firmly supported and against the tendency to rotate about 3 its longitudinal axis. It is supported against longitudinalslidably.

thrust, by a rod or plunger 32 mounted in bosses 33 and 38 on the head 12.

This rod carries a pinned collar 34 between e 32, and out of the machine,

.ing previously drawn back out ofthe way as which and the boss 33 is mounted a spring 35'whi'ch holds the collar against the boss 38. A spring 32 mounted on the boss 33 engages a wedge surface 33, holding the iron firmly against the head 12 and the rod 32'. Pressure upon the projecting rear end of the rod 32 through the lever 35 will drive it forward'against the spring 35 and cause it to knock the iron 23 forward past the spring the wheel 31 beabove described. It is clear that a hot iron can be removed quickly but without the ne-' cessity of touching it with the fingers, thus avoiding injury to the operator and permitting a tighter, firmer mounting of the iron than has been heretofore used. in this typeof machine. -A newiron'may be inserted by placing it between the projecting edges of the plates 15 and pushing it backward until the spring 32 seatsin the notch 33.

The collar 34 rests against a knurled sleeve 36 on the rod 32', which has an externally threaded portion 37 screwing into the boss 38. The knurls are engaged by a spring-pressed locking plunger 39 in the head 12. A longitudinal adjustment of the iron 23 relative to the wheel 31 is thus permitted. V i

The center of curvature of the rack 16 and the boss 14: is substantially at the intersection of the wheel 31 with the working face of the iron 23. Then the knurled head 20 is rotated the plates 15 carrying the stitchindenting wheel31 are rotated around this center so that the angle between the opera tive surfaces of the wheel 31 and the iron 23 is suitably changed without altering the regv istration of these tools relative to the work. The iron 23 is not mounted upon the plates 15 but rests againstthe lower surface of the. head 12 and remains immovable while the above-mentioned adjustment is made.

It will be noticed thatthe operative (the take in sliding along the rib 15', It will be i obvious that the. adjustment of the wheel 31 by means'of the nipple 25 merely sets an outside limit to the protrusion of the ,carrier 22 fromthe plates 15. 1 Pressure upon the outside surface of the wheel 31 willforce it backward against the spring 27so that it may respond to variations in the width of theupper surface of the sole edge, thereby allowing the sole edge to rest firmly against the iron'23 while the outside surface of the wheel 31 rests against the loweredge of the vamp. 7 Any desired means maybe to heat, the-iron 23 and wheel 31.;

Inthe illustrated embodiments of the inarranged vention, I have shown two irons.- The one, 7

shown in Figs. 1, 3 and 5 is adjustable in length by'means of a screw .40, which con-- nects its two parts {13, 4A, and has a blank 'end 42. The iron 23' shown in Fig. 4 has an edge settingsurface at 46. In Fig. 1 the machine is shown as performing a simple wheeling operation, the iron 23 acting only as an abutmentto support the sole edge against the pressureof the wheel.

, The edge setting may be done upon the'head 1 when the wheeling'is done in this manner.

If desired, the wheeling and edge setting r i may be done in one operation as shown in Fig. 4, the bevel and back at 48 supplying an abutment to support the shoe against the pressure of the wheel.

Having explained the nature of the invention and described a successful embodiment thereof, I claimas new and desire to ,se cure by Letters Patent of the United States 1. In a machine for treating the edge and top marginal faces of a shoe sole, the combination with the edge and top tools and a holder therefor, and means for fixing the adjustment of one tool in the holder with relation to the other tool, of means detachably connecting the adjustable tool with the adjustment determining means and permlttlng the tool to be removed and replaced without disturbing the adjustment.
